(01. lat-198i stand for dish washing machines of the type having a rectangular washing chamber and spraying pipes located in said chamber above and below the stand.

The object of the present invention is to provide a stand for dish washing machines of the type mentioned in which a great number of saucers and plates of difierent sizes can be se-.

curely placed in such a manner that none of the articles placed in the stand prevent completely or partially .the spraying of the surface of any other article. H

"This object is accomplished, according tothe present invention, by the arrangement and combination of elements set forth in the following detail description, defined in the appended claims and illustratively exemplified in .the accompanying drawing in which:

Fig. 1 is a top view of a stand, according to the invention,

Fig. 2 is a transverse sectional view of a dish washing machine with a stand of the type illustrated in Fig. 1 and taken on the line 11-11 of Fig. 3, and

Fig. .3 is a longitudinal vertical sectional view taken on the line III-III of Fig. 2.

The reference numeral 2 designates a front wall provided with a. handle 3 and the reference numeral 4 designates a rear wall. The said front and rear walls are connected with one another by two outer frame bars 5 and 8 and by longi-. tudinal inner bars I and 8 located between the said outer bars. so that a rigid frame is formed which substantially covers the whole bottom of the dish washing machine in which it is to be inserted during the washing operation. The frame bars 5 and B are-preferably located at about the same level, i. e., they pass through the upper, outer portions of the front and rear walls, but the inner bars I and 8 pass through the lower, intermediate portions of the said walls. The outer bars and inner bars are connected with one another by transverse rods 9. Each rod 9 has two upwardly and inwardly bent portion or elevations I located, respectively, between bars and 8 and bars 1 and 6, and a third upwardly bent portion or elevation I0 located between bars 1 and 8. Consequently, a plate ll placed between two transverse rods 9 abuts with its lower portion against the lower elevation l0 of one rod 9 and with its lateral portions against each of the two upper elevations III of the other rod 9. In the example shown, the stand comprises eleven transverse rods 9. Consequently, twelve large plates II or twenty-four dessert-plates l2 or .thirt-y-six saucers I3 can be effectively placed for spraying. When plates or the like of the same size are placed in the stand they will conseduently all be substantially parallel and located at a distance from one another which is dependent upon the mutual distance of the transverse rods 9. Large plates II, which due to their weight and their large spraying area are always difficult to arrange properly in the stand of a dish washing apparatus, will be supported at three diflerent points in the stand according to the invention. The distance between the longitudinal supports is selected in dependence upon the articles to be washed so that saucers and similar small objects come sufficiently deep down between two transverse rods.

In Figs. 2 and 3, the stand is shown placed in a suitable dish washing machine, the washing chamber of which is indicated by H; the upper spraying pipes are indicated by' l5 and the lower sprayi g pipes by l6. In the upper pipes l5 there are provided apertures which are preferably directed towards the centre line of the pipe and which form an oblique angle B to the axis of the pipe. The angle B should be so large that the spraying jet strikes the articles, such as plates placed in the stand, at an angle which is about 22, 1. e., B=68+B', where B'=the angle of inclination of the plate relatively to the vertical plane. In the lower pipes It the apertures, not shown, are located in such a way that the whole washing basket is sprayed, but the apertures are directed in such a way that the jets are formed at about to the pipe axis. Thus, the advantage is obtained that the rear portions of all plates placed in the stand which rear portions are not reached by the jets from the upper pipes are effectively sprayed by the jets from the lower pipes. In order to obtain the best cooperation between the upper and the lower jets and the most economic water consumption the number of the lower apertures is preferably of the upper apertures. The water leaves the chamber 14 through the conduit l1.

Having now described my invention, what I claim as new and desire to secure by Letters Patent is:

1. Stand for dish washing machines of the type having a rectangular-washing chamber and spray pipes located above and below the stand, said stand comprising a pair of parallel longitudinal outer frame bars spaced apart a distance slightly less than the width of the washing chamber and disposed at a common level above the bottom of the adjacent inner bar, respectively, and a third,

upwardly bent elevation between the two inner bars.

2. Stand, as claimed in claim 1, including a front and a rear end wall supporting the ends of said frame bars and inner bars.

3. Stand, as claimed in claim 1. including a front and a rear end wall supporting the ends 4 or said frame bars at the upper. outer corners of said walls, and the ends of said inner bars at points between their vertical middle lines and their lateral edges on a level slightly below their horizontal middle lines.
